摘 要:植物次生代谢在植物的环境适应,尤其是与微生物和动物的互作和防御反应中起重要作用。萜类是植物次生代谢物中最丰富的一类化合物,许多成分具有重要生理功能和应用价值。腺毛和腺体是植物次生代谢物合成、储藏和分泌的重要器官。我们实验室在植物倍半萜和单萜的生物合成途径及其调控机制、表皮毛发育与萜类代谢调控等方面取得了一系列研究进展。此外,还分析了棉铃虫对棉酚的耐受性( 适应性)反应,利用棉铃虫防御基因,发展了一种植物介导的RNAi 抗虫技术,可以有效、特异地抑制昆虫基因的表达,在植物抗虫技术研究领域有应用前景。

Abstract: Plant secondary metabolism plays an important role in plant adaptation to environment, particularly in mediating bio-interactions and protecting plants from herbivores and pathogens. Terpenoids form the largest group of plant secondary metabolites, and we are interested in sesquiterpene biosynthesis and regulation. Trichome is closely related to secondary metabolism as glandular trichomes synthesize, store and secrete/emit secondary metabolites. In this direction, we are particularly interested in transcription factors. We have analyzed the cotton bollworm response to gossypol in relation to insecticide tolerance, and developed the plant based RNAi technology for insect pest control and crop protection.
